Summary REGRESSION(290300@main): SaveAsPDF crashes if site-isolation is enabled
Marta Darbinyan
Reported 2025-02-26 10:34:44 PST
ipc/large-vector-allocate-failure-crash.html test is consistently crashing. The test is false-positive failure in EWS. The regression started within the range 291027@main...291032@main. The change 291031@main most likely the culprit based on modified files in RemoteRenderingBackend.cpp. Error logs: stderr: 7 0x3063594b4 WebCore::ImageBufferDisplayListBackend::sinkIntoPDFDocument() 8 0x30634dc84 WebCore::ImageBuffer::sinkIntoPDFDocument() 9 0x119e31db8 WebKit::RemoteRenderingBackend::didDrawRemoteToPDF(WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>) 10 0x11948d808 auto void IPC::callMemberFunction<WebKit::RemoteRenderingBackend, WebKit::RemoteRenderingBackend, void (WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>), std::__1::tuple<WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>>>(WebKit::RemoteRenderingBackend*, void (WebKit::RemoteRenderingBackend::*)(WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>), std::__1::tuple<WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>>&&)::'lambda'(auto&&...)::operator()<WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::RenderingResourceIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>, WTF::ObjectIdentifierGeneric<WebCore::SnapshotIdentifierType, WTF::ObjectIdentifierThreadSafeAccessTraits<unsigned long long>, unsigned long long>>(auto&&...) const 11 0x11948d6c8 decltype(std::declval<WebKit::RemoteRenderingBackend>()(std::declval<WTF::ObjectIdentifierGeneric<WebCore::PageIdentifierType, Test results: https://ews-build.s3-us-west-2.amazonaws.com/macOS-Sequoia-Debug-WK2-Tests-EWS/edf72f94-14110/results.html History: https://results.webkit.org/?suite=layout-tests&test=ipc%2Flarge-vector-allocate-failure-crash.html

I can repro by running these two tests back to back, but not when run individually: ./run-webkit-tests --debug --no-retry ipc/invalid-path-segments-crash.html ipc/large-vector-allocate-failure-crash.html

The same crash will be hit if we try to Save As PDF any page while `site-isolation` is enabled.

This is in fact a regression of 290300@main.
